After seeing a Synchrony CLI post, I took my chance with my CareCredit (my highest limit card).
I was at 6K (with $1700 balance on it (using the 0% interest offers))
Requested 10k and got denied but offered 7k instead.
I won't try my chance until 6 months in the future and the balance to 0, but glad I tried!
Grats on getting the CLI
